MANNING, F LOUISVILLE, KENTUCKY MATERIAL CONVEYER Application filed. February 25 1929. Serial No. 342,485.

This invention relates to a material conveying machine having the general appearance of a derrick and especially adapted for use in building construction work for elevating and conveying building materials such as bricks, mortar, cement, plaster and the like.

Briefly stated, the invention has reference to a relatively stationary tower, on which a novel unit is Vertically adjustable, said unit comprising a swinging boom, a track simultaneously movable therewith, and a. material carrier, together with means for actuating the carrier.

In carrying out the invention I have evolved and produced a novel structural organization of parts, whose functions are intimately co-ordinated in order to provide an arrangement which is efficient in performance, smooth and quite in operation, positive and dependable in action, and capable of fulfilling the requirements of an invention of this class in a satisfactory manner.

Other features and advantages of the invention will become more readily apparent from the following description and drawings.

In the drawings, forming a part of this application and wherein like reference characters designate like parts throughout the several views:

Figure 1 is a side elevational view of a material conveying machine constructed in accordance with the present invention.

Figure 2 is an enlarged fragmentary elevational View showing the hinged mounting for the boom and track.

Figure 3 is a top plan view of Figure 2.

Figure 4 is a view in section and elevation showing the supporting track and carrier structure.

Figure 5 is a diagrammatic top plan view of Figure 1, showing the variable adjustmen ts of the swingable unit.

The complete structural arrangement is shown in Figure 1, wherein it will be observed that the reference character 6 designates generally the tower. This comprises a fixedly anchored open frame work structure of appropriate elevation. including corner members in the form of angle iron 7 joined together by intersecting diagonally arranged braces 8 positioned with respect to each other to form a sort of lattice structure. Suitable guy wires or cables 9 are connected with the derrick and appropriately anchored for the sake of rigidity.

The relatively adjustable unit comprises a boom generally designated by the reference character 10 and also embodying a frame work of angle irons 11, connected by the intersecting elements 12 of a lattice work.

The inner end of this boom is hinged on a vertical pivot, as at 13, to attaching brackets let. These brackets are of the configuration shown in Figure 3 and include retaining bolts 15, engaging with the angle irons in the manner here shown. These bolts may be removed to permit the boom to be raised up and down.

Supplemental brackets 16 are attached to the tower at vertically spaced points and the vertical portion of a track 17 is indicated as at 18. This track 17 is of I-shapcd cross section and is bent intermediate its ends to provide a vertical portion and a horizontal portion. The vertical portion is disposed in spaced parallelism with the tower while the horizontal portion is disposed beneath and connected with the boom as shown plainly in Figure 4. The projecting upper and lower flanges as shown in Figure 4 provide guideways or runways for flanged rollers 19 (see Figure 4) on the material conveyer. These rollers are mounted on a substantially channel shaped carrier 20 with which a V- shaped hanger 21 is connected. The hanger is in turn connected with the bail 22 of the bucket or similar receptacle 23. In this figure the reference character 24 represents a hanger bracket carrying a sheave 25. I also direct attention to additional pulleys 26 and 27 mounted on the opposite end portions of the boom and serving to accommodate the horizontal stretch 28 of an operating cable. One end portion 29 of the cable is connected with the forward end of the carrier as shown in Figure 2, for lifting the carrier and moving it outwardly on the horizontal portion of the track. The return stretch 30 of this cable passes over sheaves 26 and 27 and (5X tends down and passes over a pulley provided with the gearing 31 operated by an appropriate source of power, for instance, an electric motor 32. The reference character 33 represents the remaining end portion of the cable which is connected to the inner end of the carrier for returning the conveyer. Any appropriate releasing and trip means (not shown) may be employed for dumping pur poses. Moreover the reference characters 34 designate suspension cables anchored on the tower and connected with the boom. Then too, as shown in Figure 5, appropriate operating elements 35 may be connected with the outer end of the boom for swinging it to the dotted line positions, here shown, or to intermediate positions. It is obvious, of course, that the boom, together with the track and conveyer, pulleys and cables, all constitute a unit which is swingable to the various positions for convenient discharge or unloading.

\Vith this arrangement, it is obvious that when the receptacle is at the lower end of the vertical portion of the track, it may be conveniently loaded with mortar or other material and the electric motor can then be started to bring the cables into play to elevate the conveyer and to carry it out on the horizontal portion of the track for unloading purposcs. As before stated, in practice, I will of course provide means whereby this clumping action can be conveniently controlled.

Then, too, means other than swinging cables 35 may be employed for adjusting the boom to various positions. It is understood, however, that the gist of this invention, is in having a complete unit embodying the conveyer, means for actuating the conveyer, and means whereby it may travel up and out within convenient reach of the workman, and further to so arrange the boom that it can be bodily adjusted in a vertical direction on thetower as the structure is built up.

A careful consideration of the description in conjunction wtih the drawings will enable the reader to obtain a clear understanding of the construction, operation and advantages.

Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in the shape, size and arrangement of details may be resorted to, in actual practice. if desired, so long as such changes do not depart from the scope of the invention or the spirit of the adjoined claims.

I claim:

1. In a material handling device for building construction work including a relatively stationary tower and a substantially horizontal boom pivotally mounted. on the tower, brackets mounted on said tower, a substantially L-shaped track having its horizontal portion fastened to the under side of said boom and having its vertical portion disposed in spaced parallelism with the tower
